Speaking about the track, Welch said: "The Queen is just this incredible character; so hungry for life but so dead inside. She's sort of eternal, but inside there's nothing. She's kind of like charcoal or something. She has this thirst for youth and for life, but for what kind of life? This darkness, but she's so beautiful, so it's this kind of juxtaposition between beauty and, ultimately, death."
The soundtrack is due for release on May 29 in the US, with the rest of the track listing still to be confirmed. Snow White and the Huntsman stars Twilight actress Kristen Stewart and Thor's Chris Hemsworth as well as Theron and is due to be released on June 1.
